A 'rro Hsin COLUMBIA FLANDURAIH co..wASHINcIToN, D. c.

are secured on same by means of nuts 25; a suitable packing being interposed to form water-tight connections.

A cold water inlet pipe 2G is preferably connected with the lowermost bell-shaped chamber ll and is just suiliciently long to extend through the bottom of same, as indicated at 27. The inner end is then capped or closed, as at 2S, and a plurality of radially disposed slots Q9 are formed in the side of the pipe to direct the incoming water against the bottom of the chamber. This prevents the formation or eliminates any tendency for mud or sediment to collect and cake on the bottom of the chamber.

For the purpose of producing the best circulation possible, as far as water is concerned, a pipe 30 connected with tbel upper end of nipple 1Q. This pipe exten .ts over the edge of the head 6 and is then turned down, as indicated at 3l, to force the water down to'warr the bottom of the annular chamber 5. A vent formed in the bend of the pipe prevents any tendency lto form a steam pocket in the pipe 30.

rlhe ret-urn pipe from the hot water pipe system, indicated at 33, is preferably connected with a thermostat valve, such as indicated at 3l. rlhis valve regulates the flow of gas to burner 18 as it is directly connected with valve 35 on the gas main. The moment the water in the system attains a predetermined degree of temperature or heat it will cause the thermostatic valve to expand and correspondingly open or close the valve 35, thus automatically regulating the burner i8.

Each sectionl and 3 is provided with a clean-out connection 36 to remove any sediment which might have a tendency to collect in the lower portion of the annular jacketlilre chamber 5 and one or more doors, such as indicated at 3'3", may be provided in the spacing ring 13 to permit the cleaning out of the heating flues, etc.

Formed in the cover section 21 is a plurality of openings 2la and a baille-plate 2lb. The barile-plate is provided for the purpose of preventing any down draft through the heater. Any down draft coming through vent 22 will strike the annular baille-plate 2lb and will immediately pass out through the openings 21a. The elimination of the down draft protects the several heating surfaces from sudden changes of temperature, thereby preventing contraction and also protecting the pilot light and burner from being extinguished.

The l eater, when assembled, is preferably protected by a sheet metal casing, such as indicated at 39, which is lined with asbestos cloth, thus insuring against loss of heat from the hot water which might otherwise be radiated. While the heater is here shown as constructed of two sections, it will be understood that it may be increased by adding on any suitable number of sections to those already in use. rEhe hot water return pipe connected with the lower' section, as indiyfated at Ll0, will act as a booster to cause an innnediate return of water to the heater frcm the het water pipe system, thereby insuring instant hot water at all liXtures connected with the system.

j'r heater constructed as here shown is simple and substantial in construction and is easily accessible for cleaning and repairing. The large heating surface provided throughout the several sections and chainbers formed within the heater permits practically every heat unit to be absorbed by the water, thus greatly increasing the eiiiciency and capacity of same. l'"ie heater can, furthermore, be easily dismantled, as it is only necessary to loosen the coupling and the slip joint Interchanging or renewal of the several parts, when necessary, can thus be easily accomplished.

The materials and finish of the several parts of the heater are such as the experience and judgment of the manufacturer may dictate.

il wish it understood that Various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims and that l do not wish to limit myself to the specilic design and construction here shown.

Having thus described my invention, what l claim and desire to secure by Letters Patent isl. A water heater comprising, in combination, a casing having a central heating chamber formed therein and an annular jacket-like water chamber exteriorly of the heating chamber, a head closing the upper end of the heating chamber, a plate closing the upper end of the casing, flues extending through the head and plate communicating with the heatino chamber, a bellshaped, hollow casing centrally positioned within the heating chamber, a nipple connecting same with the annular water chamber, a water inlet pipe connected with the bellshaped casing, and an outlet pipe connected with the head.

2. A water heater comprising, in combination, a casing having acentral heating chamber formed therein and an annular jacket-like water chamber exteriorly of the heating chamber, a head closing the upper end of the heating chamber, a plate closing the upper end of the casing, flues extending through the head and plate communicating with the heating chamber, a bell-shaped, hollow casing centrally positioned within the heating chamber, a nipple connecting same with the annular water chamber, a water inlet pipe connected with the bellshaped casing, said pipe extending into the 'l lll@ chamber formed interiorly of the bell* shaped casing and having a plurality of radially disposed discharge slots formed therein, and an outlet pipe connected with the plate.

3. A water heater comprising, in combination, a casing having a central heating chamber formed therein and an annularI jacket-like water chamber exteriorly ot the heating chamber` a head closing the upper end of the heating chamber, a plate closing the upper end of the casing, tlues extending through the head and plate communicating with the heating chamber, a bell-shaped, hollow casing centrally positioned within the heating chamber, a nipple connecting same with the annular water chamber, a cover casing mounted above the plate, a hollow baille-shaped casinO mounted interio-rly of said casing, a nipple connecting the lower' end of the baille-shaped casing with the plate to form communication with the annular water chamber, an outlet pipe connect ed with the upper end of the baille-shaped casing, and an inlet pipe connected with the bell-shaped casing.`

4. A water heater comprising, in combination, a casing having a central heating chamber formed therein and an annular jacket-like water chamber exteriorly of the heating chamber, head closing the upper end ot the heating chamber, a plate closing the upper end of the casing, lues extending through the head and plate communicating with the heating chamber, a bell-shaped, hollow casing centrally positioned within the heating chamber, a nipple connecting same with the annular' water chamber, a cover casing mounted above the plate, a hollow baille-shaped casing mounted interiorly of said casing, a nipple connecting the lower end of the balile-shaped casing with the plate to form communication with the annular water chamber', an outlet pipe connected with the upper end of the bailleshaped casing, an inlet pipe connected with the bell-shaped casing, a vent pipe connected with the cover casing, and means 'for preventing a down d aft through the cover easing.

5. A heater ol' the character described, comprising, in combination, a plurality of superposed casings, each having a central heating chamberv formed therein and an annular jacketdike water chamber exteriorly of the heating chamber, a head closing the upper end of each heating` chamber, a plate closing the upper end of each casing, a spacing ring interposed between each casing, a burner mounted in the lower heating` chamber', a plurality of :lines extending through each plate and head to permit the heat to pass through the several heating chammers, a battle-shaped, hollow casing mounted above each plate, connections formed between each annular jacket-like vwater chamber and battle-shaped casings to permit the water as itheats to circulate in an upward direction through the several connected chambers, an outlet pipe connected with the uppermost baiileshaped casing, and a water inlet-pipe connected with the lowermoet annular jacket-like water chamber.

ln testimony whereof l have hereunto set my hand in the presence of two subscribing witnesses.
